JOSEPH H. DICKINSON, OF ORANFORD, NEW JERSEY, ASSIGNOR TO AEOLIAN OOMPAN Y,

NEW YORK, N. Y., A CORPORATION OF CONNECTICUT.

PUPPE T-VALVE To all whom it may concern:

Be it known that I, JOSEPH H. DICKINSON, a citizen of the United States, and a resident of Cranford, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Pu Valves, of which the following is a speci cation.

This invention relates to improvements in puppet 'valves and more particularly to the puppet valves such as are used for controling the passage of air into and out of the motor pneum'atics, such as are used in pneumatic players for musical instruments.

The ob ect of my invention is to simplify the construction of the puppet valve and to facilitate-the adjustment of the same and also to insure the greater reliability and durability of the valve.

In the accompanying drawing 'Figure 1 represents a motor pneumatic with its controlling puppet valve, embodying my inven= tion. Fig. 2 is a lan view of the screw cup. Fig. 3 is a vertica transverse sectional view of the same. Fig. 4 is a lan View of the cross piece and the washer .ield in the same, Fig. 5 is a vertical transverse sectional view of the cross piece.

The motor pneumatic or bellows 1, the air assages 2, 3 and the dia hragm 4, and-the ibwer valve seat 5 are al of conventional construction. The uppet valve 6 is also made of conventional construction and pref erably consists of a disk of metal with felt washers at the top and bottom, said valve being secured on a stem 7 which moves u and down under the action of the air-of di[ erent pressure actin on the dia hragm 4. Ascrew cup 8, preferably made o f metal, is provided in its u per ed e with notches 9 for inserting .an imp ement y means of which the screw cup 8 can be screwed up or down in a threaded openingin the valve casing or box 10 for a purpose t at will appear hereinafter. The screw cup 8 is rovi ed with a bottom opening 11 and wit a flat under surface against which the top of the valve 6 can seat for the urpose of closing or opening the opening 11 ormed in the bottom of the screw cup and by means of whichopening the communication between the neumatic bellows 1 and the outer air is estab ished. A recess or groove 12 is cub'in the inner surface of the screw on at or about halfthe height of the same. 5

cross piece 13 made of thin brass has its ends so shaped that they can fit into this groove and this member or cross piece 13 has sufficient elasticity as to permit of its being bent and sprung into the notch or groove in the screw cup, that is to say, the ends of the cross piece or member 13 are s rung mto the notch or groove 12 so as to old the cross piece securely within the cup. The cross piece is provided with a centra depression or dished part 14 having a central opening 15 through which the stem 7 can pass. A felt Washer 16 having an openingof proper size for properly. guiding the stem 7 is placed into the recess or depression 14 and confined within the same by means of tongues 17 which are struck up integral with the cross piece 13 and then are folded'over the washer 16 so as to hold the same in place. By means of a wrench or other tool applied in the notches 9 the screw cuv can easily be adjusted vertically so that tile top of the puppet valve will seat. roperly on the underside of the cup 8 when tliis valve is forced upward by air actin on the diaphragm 4.

Having escribed my invention what I claim as' new and desire to secure by Letters Patent is 1. The combination with a puppet vntve and stem, and means for o crating the valve, of a cup having internal recesses, a cross piece s rung into said recesses and forming a guide or the upper end of the'valve stem, substantially as set forth.

2. The combination with a pu pet valve,

a stem, and means for operating t e valve, of a cup having internal recesses, a cross piece sprung into therecesses and having a central I portion and a, washer secured in'said central portion, substantially as set forth.

3 The combination-with a puppet valve and stem, andineans for o crating the valve, of a cup having internai recesses, a cross piece sprung into said recess and having a dished central portion and prongs, awasher laced in said. dished portion, the prongs being bent over the was er to hold the same in place, substantially as set forth.

4. The combinationwith a puppet valve and stem and means for moving the puppet valve, of a cup forming the seat for the top of the valve, 8. cross piece on said cup which cross piece is provided with prongs, a washer on said cross piece, the prongs being bent I i 2 sas,su7

over the washer. to hold the same in place, guide for the valve stem, substantially as set substantially as set forth. forth.

5. The combination with a uppet valve Signed at New York city in the county of and stem, means for operating t e valve, of a New York and State of New York this 17th 5 scrlew cu firming}? seat fcg the top of the day of Sept-ember, A. D. 1907.

Va ve, w 0 cup as note es in its up er v i v edge for applying animplement for turning JOSEPH the cup, a cross piece held on said cup and Witnesses: provided with rongs, and a washer held on A. W., SPEN ER, 10 the cross piece y said prongs and forming a F. H. HUGHES.
